NEST 50 mL Centrifuge Tube (500 count)

Overview

• Detection kits for Giardia intestinalis
• CE-IVD marked version available for in vitro diagnostic use
• Available in TaqMan format for analysis.

Giardiasis is a disease of the small bowel caused by the protozoan parasite Giardia intestinalis (syn.duodenalis or lamblia). Giardia is one of the most common intestinal parasites in the world, and occurs at very high prevalence rates in places with poor water sanitation. Individuals become infected through ingesting or coming into contact with contaminated water, food or soil. It can also be spread through the faecal-oral route due to poor hygiene practices, which makes it common in day-care centers. G. intestinalis lives inside the intestines of infected humans or other animals including cats, dogs, birds, cows, beaver and deer. Symptoms of infection include diarrhea, malaise, excessive gas, bloating, nausea, diminished interest in food, possible vomiting and weight loss.

There are 2 kits available for the detection of Giardia intestinalis:

Giardia intestinalis TaqMan RT-PCR Kit, 100 reactions

• Ready to use format, including Master Mix for the target and PCR control to monitor for PCR inhibition and validate the quality
• Specific Primer and Probe mix for the pathogen/virus/viroid of interest
• Primer and Probe mix
• Positive and negative control to confirm the integrity of the kit reagents

Giardia intestinalis TaqMan RT-PCR Probe/Primer Set and Controls, 100 reactions

• Specific Primer/Probe mix and Positive Control for the pathogen/virus/viroid of interest
• Nuclease-free water
• Can be used together with Norgen’s RT-PCR Master Mix (#28113) or customer supplied master mix

Storage Conditions and Product Stability
All kit components can be stored for 1 year after the date of production without showing any reduction in performance.

All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

Introduction

Usages:
For isolating lactose-fermenting Gram-negative enteric bacilli.

Principle:
Peptones are sources of nitrogen and other nutrients. Lactose is a fermentable carbohydrate. When lactose is fermented, alocal pH drop around the colony causes a color change in the pH indicator (neutral red) and bile precipitation. Bile salts,bile salts no. 3, oxgall and crystal violet are selective agents that inhibit growth of gram-positive organisms. Agar is the solidifying agent.

Formulation（per liter）:

Pancreatic Digest of Gelatin	17.0 g
Peptones (meat and casein)	3.0 g
Lactose Monohydrate	10.0 g
Sodium Chloride	5.0 g
Bile Salts	1.5 g
Agar	13.5 g
Neutral Red	30.0 mg
Crystal Violet	1 mg
Final pH	7.1±0.2

How to use：
1.Suspend 50 g in 1 L of distilled or deionized water. Heat to boiling to dissolve completely. Autoclave at 121°C for 15 minutes.

2.Transfer 1 mL of Soybean–Casein Digest Broth to 100 mL of MacConkey Broth, and incubate at 42 to 44 for 24 to 48 hours. Subculture on a plate of MacConkey Agar at 30 to 35 deg.C for 18 to 72 hours.

Quality control：
